To all whom t llt/tj; oon/cern,.-

Be it known that I, ARTHUR SenLUTER., a oitizen of the United States of America, residing at W'aunakee, in the county of Dane and State of Wisconsin, have invented new and useful Improvements in Pumps, of which the following is a speeiiieation.

The invention relates to an improvement in pumps, and partieularly to a governor therefor designed in operation to secure a steady even movement of the piston-rod in operation.

The main object of the present invention is the provision of adjustable, means arranged to eounterbalanee the weight of the pumprod, whereby to insure a steady and even reeiproeation thereof under power or hand operation.

The preferred embodiment of details of the resent invention will be described in the folowing specification, reference being had particularly to the accompanying drawing, which illustrates in side elevation a pump having a governor constructed in accordanee with my invention.

Referring to the drawing, wherein like reference-numerals indicate like parts throughout,1 represents a pump-easing 5 2, the pumprod; 3, the handle-bracket, and 4 the handle, pivotally connected at its inner terminal to the pump-rod at 5 and fulcrumed at 6 on the handle-bracket. All these parts may be of any usual or preferred eonstruetion, as they form no material part of the present invention, the handle-bracket 3, however, being, by preference, provided at its upper end with a sleeve or bearing 7 to receive and guide the pump-rod 2.

In carrying out my invention I provide a U-shaped frame 8, centrally formed with an opening 9, adapted to be passed longitudinally on the pump-rod 2 and rest upon the sleeve 7 of the handle-bracket, a braee 1U secured to one of the arms of the frame 8 and to the pump-easing serving to prevent independent movement of the frame.

11 represents a oog-plate comprising a body portion formed with a longitudinallyarranged openin and to engage the pumprod, said plate being secured in adjusted position through the medium of set-screws 12. By preference, the upper end of the pumprod is square in cross-section, and the opening in the body ot' the cog-plate is also square to lit the pump-rod, though it is to be understood that l contemplate the use of a cogplate in connection with pump-rods of any sectional een tour. The body of the oogplate is provided on its longitudinal edges with vertienlly-extending arms 13, formed or provided on their outer edges with cogs or teeth 14. The arms 13 extend above the body of the plate, but are spaced from the pump-rod, whereby to provide for a ready Connection of the operating-arms or lengths from a gas-engine or other power-machine.

ihe free ends olE the arms of the frame 8 are bitureated, and in the bifurcations are j)ivotally-supported levers 15, which when in position on the frame project outwardly and downwardly therefrom on a gradual Curve, as illustrated. The inner ends of the levers 15 are provided with transversely-arranged segments 16, having on their edges next the pump-rod a series of teeth 17, arranged to operatively intermesh at all times with the teeth 14 on the armslS of the cogplate. A weight 18 is slidably mounted on the free end of each of the levers 15, being held in adjusted position lengthwise said lever by a set-screw 1).

In operation the reeiproeatory movement of the pump-rod under the iniiuenee of a power-machine or of the handle 4 will be eifeotively eounterbalaneed by the weights 18, insuring an even steady movement of the pump-rod and obviating the jerking ordinarily incident to its movement when free of a governing mechanism. The weights 18 may be adjusted lengthwise the levers 15 to provide the emnpensation desired, the movement of the weights toward the free end of the leversl increasing, of Course, their counterbalaneing ell'eet.

The structure deseribed is simple and may he readily ap )lied to puni i structures now in use without e ange in their details.

` Having thus described the invention, what 1 elaim is The combination with a pump having a handle-bracket provided with a guidingsleeve, a pump-rod o erating through sald sleeve, and a hand e pivoted upon the bracket and operatively eonneeted with the pump-rod, of a U-shaped frame supported brace connecting the Usshaped. frame with upon the handle-bracket and havingjr an openthe handle-bracket and assembling the parts.
